Recently the all 3 lights for the ACD have come on.

It came on and went away over the course of a day or so here and there, not every time I got in but 50% of the time While I was waiting to get into the dealer.

Took the car into the dealer and had them take a look at it. Their response was " well the pump is working, we reset the acd and it still is causing a code come up saying the pump is not operating. So we think it is in the wire harnes"

My response was "wire harness? which one?"

Their response "anywhere throughout the car, we dont really know, but we think it is electrical."

Now this conviently started about 1 week after I attended a track day, In which I bled the brakes the day before and intalled new ferrodo pads. I am not sure if its related to putting the car through its paces at the track, but just thought I would present all the info I have.

I do notice that lots of guys have problems after installing a clutch, with the lights then coming on, and the ACD system needing to be re-bled.
Could this be the case here or is there indeed a possible electical problem (switch, wiring and etc...)?


I am just looking for some one with a comparible experience possibly or any insight at all.

Thanks in advance

I would change the tc oil and have it re-bled. Don't drive the car around if all three lights are on it could get expensive.

 

Bump.

Nobody else ever have this issue?

 

search, I swear I have seen this issue come up 2 or 3 times.

 

same exact thing happened to me. The dealer ended up changing my pump, problem solved. I had never herad or this happening before

 

Happened to me and it was just a fuse...not sure which one but check the easiest things first before you fix the pump...

 

check the resovoir (sp) level. if it drops below the low level mark on the bottle all the lights will come on. it is located right behind your drivers side head light. i use castrol ATF. good luck.

 

Okay thanks, I checked all the fuses and none are blown taking it back into the dealer hopefully on Tues. They say its an electrical problem..... I am guessing the pump has **** the bed or something...

Thanks and bump for any more info/ideas

UPDATE:

Car has been at the dealer for the past 2 days. They have not figured out anything. They are not happy with the gauges in the car (defi BF's) and the aftermarket radio and exhasut. But they did not really care about the exhaust and knew it would not hinder the acd issue.

A factory rep was there today working with the Mechanics and they were working with the tech. Line out of cali trying to figure it out... and still nothing.

They want me to take out my guages and radio to eliminate any possible problems and return the car to exactly stock and diagnose from there.

So it will be going back into the shop agggaaaiiinnnn.

I will update agian when I find out more...
Wish me luck

 

No gauge would interfere with that, neither would the radio. Tell them to actually do some work and quit trying to make excuses. What gauges do you have BTW? I am assuming nothing that remotely deals with your ACD so not following their logic on that one.

 

I completly agree but they think its an electrical problem of some sort and since the gauges are aftermarket and thus is the radio, they want them out. Thats fine, not a problem, still a PITA though. I have Defi BF's.

I have a feeling that its not electrical, but more than likely the pump-related...
I will update when I get it back in next week.

UPDATE:

Dealer has replaced my ACD Pump. It was not a cheap item covered under warranty of course

I have had the car back for 2 days now and everything is fine thus far

Just thought I would update for anyone else in the future that may need help. I have only heard of one other person that has had this failure.

damn they replaced the entire unit? crazy... Did you do anything else specific before the issue came up or are you really hard on the drivetrain?

 

I think he means ACD ECU. You need to be more descriptive.

 

Sorry, I mean the ACD PUMP. Fixed it ^
